Y2: Science

In our Science lessons this year, we are beginning to explore the mysterious world of materials, their properties, every day uses and what makes them suitable or unsuitable for particular purposes. 

 

 We will work scientifically by: comparing the uses of everyday materials found at home, out and about on our daily exercise as well as those found in stories, rhymes and songs; observing closely, identifying and classifying the uses of different materials, and recording our observations.

Lesson 1: What is the difference Between a Solid, Liquid and Gas?

Hopefully you have had the chance to look around your house to find some examples of a solid, liquid and gas. Don't worry if you haven't yet. Have a watch of the lesson below (click on the link) and then you can put your detective skills to the test to see what you can find.

 

You have two activities to complete as part of this lesson. For the first one you will need to use the three circles labelled solids, liquids and gas. Sort the items in to the correct circle. You can add some of the additional items you have found at home in to the circles as well.

Next you need to draw what the particles look like inside a solid, liquid and a gas. This part is very important as it is the reason why things behave in the way that they do. A solid has tightly packed particles which means it is extremely difficult to change its shape unless you apply lots of pressure. A liquid on the other hand has particles which have room to move about which means that they can take on the shape of any container that they are poured in to. 

Finally, have a go at the end of lesson quiz to see how much you have remembered.

Lesson 2: What happens when you heat a solid?

 

Have a think about this question before you begin the lesson and make a prediction. What do you think happens when you heat a solid?

 

Here are some examples of solids which you might find at home in your kitchen. What do you think would happen to them if heat was applied? Do you think they would melt?

 

  

 

What does melted mean?

 Is it possible to melt a solid?

Can all solids be melted?

 

Watch the video below to learn about what happens when you heat a solid. There are some recording sheets too, but you can just record your learning on a piece of paper with a pencil.

Lesson 4: What happens when I mix a solid and liquid together?

 

Watch through the lesson video below and use the recording sheet to note down any observations you make as a solid and liquid are mixed together. Some key vocabulary you are going to learn about include:

 

soluble

insoluble

dissolve 

 

When you have watched the experiment, have a go at carefully carrying out your own experiment at home. You will need an adult to help you.
